Description

Technical Field

[0001] The utility model relates to the field of printers, in particular to a protective structure. Background Art

[0002] During the ejection step of the medical film, the film needs to be placed in the film box, then the protective door is opened, and then the film box is installed inside the equipment. When the film box is installed in place, the protective door is closed and the equipment is running to prevent the equipment from starting to operate when the film box is not installed in place or the protective door is not closed in place, causing injury to the operator or damage to the film box.

When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may be another intermediate component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be another intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0025] A protective structure is used to detect whether the protective door 20 is properly installed, prevent the sensor from being triggered by mistake, and improve production safety. In this embodiment, the protective structure is applied to film processing equipment. In other embodiments, the protective structure can also be applied to other equipment, which is not limited here.

[0026] See also Figures 1 to 4 A protective structure includes a shell 10, a protective door 20, a first mounting member 30, a second mounting member 40, a first sensing device 50, a second sensing device 60, a bracket 70, a film box 80, a baffle 90 and a position sensing device 100.

[0027] The housing 10 is a hollow structure, and a space for installing processing equipment is provided inside the housing 10. The housing 10 is provided with an opening 11, and the opening 11 is used for the product to be processed to enter the housing 10. In this embodiment, the product to be processed is a film.

[0028] Protective door 20 is mounted on housing 10 and is used to close opening 11 during processing of the product to prevent operator injury, environmental contamination of the product, and waste generated during processing from splashing out of the equipment through opening 11. In this embodiment, protective door 20 is inserted to cover opening 11. In other embodiments, protective door 20 can also be mounted on housing 10 through a rotating or sliding connection.

[0029] The first mounting member 30 is fixed to the housing 10. The first mounting member 30 is used to mount the protective door 20. When the protective door 20 is mounted on the first mounting member 30, the opening 11 is covered by the protective door 20. In this embodiment, the first mounting member 30 is a support block, and a mounting groove is provided on the top of the support block 30. The top of the protective door 20 can be mounted in the mounting groove. Specifically, there are two first mounting members 30, and the two first mounting members 30 are located on both sides of the top of the opening 11. Mounting rods are provided at both ends of the top of the protective door 20. When the mounting rods are placed in the mounting grooves, the protective door 20 is mounted on the first mounting member 30, and the opening 11 is covered by the protective door 20.

[0030] The second mounting member 40 is fixed to the housing 10. The second mounting member 40 is used to place the protective door 20 when the opening 11 is opened to prevent the protective door 20 from having nowhere to be placed. The second mounting member 40 is a support block, and a mounting groove is provided on the top of the support block. The top of the protective door 20 can be installed in the mounting groove. Specifically, there are two second mounting members 40, and the two second mounting members 40 are located on both sides of the top of the opening 11 and are greater in height than the first mounting member 30. Mounting rods are provided at both ends of the top of the protective door 20. When the mounting rods are placed in the mounting grooves, the protective door 20 is mounted on the second mounting member 40, and the opening 11 is opened.

[0031] The first sensing device 50 is fixed at the right end of the bottom of the opening 11 . The first sensing device 50 is a photoelectric sensor or a pressure sensor. When the protective door 20 is installed in place on the housing 10 , the protective door 20 covers the first sensing device 50 or presses against the first sensing device 50 .

[0032] The second sensing device 60 is fixed to the left end of the bottom of the opening 11 . The second sensing device 60 is a photoelectric sensor or a pressure sensor. When the protective door 20 is installed in place on the housing 10 , the protective door 20 covers the second sensing device 60 or presses against the second sensing device 60 .

[0033] Bracket 70 is rotatably mounted within housing 10. Bracket 70 is driven to rotate relative to housing 10 by a drive mechanism. The drive signal from the drive mechanism is controlled by signals from first sensing device 50, second sensing device 60, and position sensing device 100. Bracket 70 accommodates film cassette 80, thereby driving its rotation. Specifically, bracket 70 is provided with a slide rail, and film cassette 80 is slidably mounted to bracket 70.

[0034] The film box 80 is used to install stacked films (products to be processed). The film box 80 is placed into the housing 10 through the opening 11.

[0035] The barrier 90 and position sensing device 100 are used to monitor whether the film cassette 80 is properly installed. Specifically, the barrier 90 is fixed to the end of the side of the film cassette 80, and the position sensing device 100 is fixed to the bracket 70. When the film cassette 80 is properly installed, the barrier 90 triggers the position sensing device 100. Specifically, the position sensing device 100 is a photoelectric sensor.

[0036] When the protective structure is in use, the protective door 20 is removed from the first mounting member 30 and placed on the second mounting member 40. The opening 11 is now open, and the film is installed in the film box 80. The film box 80 is slidably mounted on the bracket 70. When the film box 80 is in place, the barrier 90 triggers the position sensing device 100, generating a signal. The protective door 20 is removed from the second mounting member 40 and placed on the first mounting member 30. When the protective door 20 is in place, both the first sensing device 50 and the second sensing device 60 are triggered. The bracket 70 can now be driven to rotate by the driving member, thus preventing the first sensing device 50 or the second sensing device 60 from being blocked by other objects or people, thereby preventing the protective door 20 from being in place and the device from operating.

[0037] The above embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that those skilled in the art will be able to make various modifications and improvements without departing from the spirit of the present invention. These modifications and improvements are equivalent to those made to the above embodiments based on the essential technology of the present invention and fall within the scope of protection of the present invention.
